BACKGROUND

The present disclosure relates to beds and in particular to beds that can be varied in size. More particularly, the present disclosure relates to a frame that is configured to support a mattress and that can be reconfigured to support mattresses of various sizes.

SUMMARY

The present disclosure relates to a bed including a mattress-support frame. In illustrative embodiments, the mattress-support frame can be reconfigured in the field by a person to change the size and shape of the frame so that a relatively smaller mattress can be supported on the frame to establish a toddler-bed mode of the bed or a relatively larger mattress can be supported on the frame to establish a twin-bed mode of the bed. It is within the scope of the present disclosure to convert the frame to support mattresses of all sizes.

In illustrative embodiments, a convertible bed includes a mattress-support frame comprising components that can be moved relative to one another by a person in the field to change the width and/or the length of the frame. The convertible bed also includes a releasable lock system for locking movable pieces included each of those components relative to one another to establish, for example, a toddler-bed mode in which the frame has a relatively narrow width and short length that is sized to support a toddler-bed mattress, or, at the option of the user, to establish, for example, a twin-bed mode in which the frame has a relatively wider width and longer length that is sized to support a twin-bed mattress.

In illustrative embodiments, the convertible bed includes a variable-width headboard, a variable-width footboard, and variable-length side walls arranged to lie in laterally spaced-apart relation to one another and to interconnect the headboard and footboard. The convertible bed also includes a variable-width mid-section arranged to interconnect the side walls. In illustrative embodiments, the headboard, footboard, side walls, and mid-section are part of a convertible bed kit that also comprises a set of relatively short toddler-bed slats for underlying and supporting a toddler-bed mattress when a toddler-bed mode of the bed is established and a set of relatively longer twin-bed slats for underlying and supporting a relatively larger twin-bed mattress when a twin-bed mode of the bed is established.

In illustrative embodiments, each of the variable-width headboard, footboard, and mid-section comprise first and second movable segments that can be moved relative to one another when unlocked to vary the width of the headboard, footboard or mid-section. The headboard comprises interlocking E-shaped and Pi-shaped movable headboard segments while the footboard comprises interlocking C-shaped and T-shaped movable footboard segments.

In illustrative embodiments, the convertible bed kit in accordance with the present disclosure also includes a headboard segment-motion lock comprising top and bottom toddler-bed headboard caps and relatively longer top and bottom twin-bed caps. In the toddler-bed mode, the relatively short toddler-bed headboard caps are selected from the kit and mounted by the caregiver on the drawn-together first and second movable headboard segments to lock those segments to one another to establish a narrow-width headboard. Alternatively, in the twin-bed mode, the relatively longer twin-bed headboard caps are selected from the kit and mounted by the caregiver on the spread-apart first and second movable headboard segments to lock those segments to one another to establish a wide-width headboard. Similarly, the convertible bed kit also includes short top and bottom toddler-bed footboard caps and relatively longer top and bottom twin-bed footboard caps for use in locking the movable footboard segments of the footboard together when drawn together to establish a narrow-width footboard or when spread apart to establish a wide-width footboard.

Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
